I recently acquired this JP7, which EBMM tells me was born in December 2004. They also say that guitars around that time were built with a Custom Dimarzio in the neck and a D-Sonic in the bridge. But I've only ever seen D-Sonics with the metal "bar" on them.
Could it be that 7-string D-Sonics once came without the "bar", or could this have be an aftermarket pickup?
